The Stages of Mitosis (Answer Key)
Directions
The diagrams below illustrate the stages of mitosis. Place the correct name of each stage on the
accompanying line and fill in the missing labels for the parts of the cell. Then, briefly describe
what is happening in each stage in the chart below.
cell membrane
chromosomes
spindle fibers
nucleolus
chromatid
cell membrane
cytoplasm
A
Interphase
nuclear envelope
B
Prophase
C
Metaphase
chromatid
centriole
F
Late Telophase
E
Early Telophase
D
Anaphase
A
Interphase - Chromosomes replicate and pair up as chromatids (original cell (2 chromosomes) →
2 pair (4 chromosomes)).
B
Prophase - Sister chromatids condense, thicken and become visible, nuclear envelope disappears.
C
Metaphase - Chromatids move toward center of cell and line up at equator, spindle fibers attach to
centromeres.
D
Anaphase - Centromeres of each chromatid separate and are pulled toward poles of cell (2 chromosomes to each cell).
E
Early Telophase - Nuclear envelope reforms around chromosomes, cell membrane furrows.
F
Late Telophase - Cytokinesis takes place forming daughter cells.
